13. Let us therefore keep the feast, my brethren, celebrating it not at all as an occasion of distress and mourning, neither let us mingle with heretics through temporal trials brought upon us by godliness. But if anything that would promote joy and gladness should offer, let us attend to it; so that our heart may not be sad, like that of Cain; but that, like faithful and good servants of the Lord, we may hear the words, ‘Enter into the joy of thy Lord.’ For we do not institute days of mourning and sorrow, as some may consider these of Easter to be, but we keep the feast, being filled with joy and gladness. We keep it then, not regarding it after the deceitful error of the Jews, nor according to the teaching of the Arians, which takes away the Son from the Godhead, and numbers Him among creatures; but we look to the correct doctrine we derive from the Lord. For the guile of the Jews, and the unbounded impiety of the Arians, cause nothing but sad reflections, for the former at the beginning slew the Lord; but these latter take away His position of having conquered that death to which the Jews brought Him, in that they say He is not the Creator, but a creature. For if He were a creature, He would have been holden by death; but if He was not holden by death, according to the Scriptures, He is not a creature, but the Lord of the creatures, and the subject of this immortal feast.
